Abstract
Description
Technical Field
[0001] The present invention relates to the field of wave dissipation and power generation, and in particular to a floating wave dissipation and power generation device. Background Art
[0002] The Yangtze River Estuary has a long coastline, and waves can cause disasters, constantly eroding the coast and embankments, necessitating wave protection and wave breaking. Traditional wave breaking methods are all confrontational, with wave-breaking components simply stacked on the beach or outside the embankment. Due to the limited stacking height of wave-breaking blocks (such as twisted I-shaped blocks), they can only reduce waves below a certain tide level and are ineffective above that level. In reality, high tides create greater winds and waves, making wave breaking even more necessary. On the other hand, waves possess kinetic energy and are a clean, renewable energy source. Wave-powered power generation technology is currently under development. However, relevant data indicates that all wave-powered power generation technologies only provide single-use power and have low utilization rates.
[0003] In summary, traditional wave dissipation methods suffer from the drawbacks of passive wave dissipation. Waters requiring wave dissipation often have the potential for wave power generation. However, if wave dissipation is solely implemented to protect seawalls and other projects, the wave's energy resources are wasted. Furthermore, traditional wave power generation and wave dissipation both function independently, and single wave dissipation and power generation devices have yielded suboptimal results, high material and construction costs, and high power generation costs, making them difficult to meet the development requirements of marine projects.

Under any working conditions, the top of the blade on the upper part of the drum box is higher than the static water level of the water area.
[0006] Furthermore, there are multiple pile shafts, which are arranged in a row in a straight line or a broken line, and a roller device is provided between the buoy devices on two adjacent pile shafts.
[0007] Furthermore, in the roller device, multiple roller boxes are installed on a single horizontal axis, and each roller box is installed with a power generation component. The roller device also includes a limiting axis card fixed on the horizontal axis and located between adjacent roller boxes. The limiting axis card is used to limit the axial displacement of the roller box.
[0008] Furthermore, the buoy device includes a closed cylindrical hollow box body consisting of an inner sleeve, an outer sleeve, a bottom plate and a top plate, and the inner sleeve is movably mounted on the pile shaft.
[0009] Furthermore, a plurality of grooves are provided on the inner hole wall of the inner sleeve along its circumference, and balls are provided in the grooves to abut against the pile shaft (1).
[0010] Furthermore, the cylindrical hollow box body also includes a reinforcing rib plate connecting the inner sleeve and the outer sleeve.

[0016] By installing a pile shaft, buoys, and a drum, the floating wave-breaking power generation device is assembled in the waters requiring wave protection. When waves form on the water surface and surge toward the protected embankment or shore, they are intercepted when they contact the device. Because wave energy is concentrated on the surface, the blades absorb the waves. Under the impact of the waves, the drum housing rotates continuously around the horizontal axis. During this rotation, the blades continuously break up the waves, breaking large waves into smaller ones. Under the action of subsequent waves, the drum housing continues to rotate, thus continuously breaking up the waves and dissipating energy, effectively eliminating waves with waves. The drum housing's rotation around the horizontal axis drives the rotor of the generator assembly around the stator, generating an induced current, thus harnessing the power of the waves. As the tide rises and falls, the buoys adjust the height of the horizontal axis and the drum housing to ensure that the drum housing remains in the optimal position for wave breaking and power generation. The floating wave-breaking and power generation equipment of the present invention can not only prevent and eliminate waves, but also generate electricity using waves. It combines wave prevention and power generation into one, turning harm into benefit and making full use of wave resources. It can also automatically adjust its height as the tide level changes to ensure the best working effect. BRIEF DESCRIPTION OF THE DRAWINGS

Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.
[0055] See also Figures 1 to 9The present invention provides a floating wave-breaking power generation device, which is used to be set in waters that need wave protection and can be arranged linearly along the shore of the wave-breaking area. The floating wave-breaking power generation device includes a pile shaft 1, a buoy device 2, and a roller device 3. The pile shaft 1 is vertically driven into the bottom foundation 6 of the water area. There are at least two pile shafts 1, and there is a certain distance between the pile shafts 1. Each pile shaft 1 is equipped with a buoy device 2, and the buoy device 2 can move up and down along the pile shaft 1. The roller device 3 includes a horizontal shaft 31, a roller box 32 rotatably mounted on the horizontal shaft 31, and a power generation component installed in the roller box 32. The two ends of the horizontal shaft 31 are respectively fixedly mounted on the two buoy devices 2. The outer circumference of the drum box 32 is fixed with dispersed blades 33. The drum box 3 2. A water-isolating structure is provided between the ends of the drum housing 32 and the horizontal shaft 31, creating a sealed accommodation space between the drum housing 32 and the horizontal shaft 31. The power generation assembly includes a rotor 35 and a stator 34, all located in the accommodation space, as well as a transmission cable 36. The stator 34 is fixed to the horizontal shaft 31, and the rotor 35 is fixedly mounted on the drum housing 32 and surrounds the stator 34. When the rotor 35 rotates, electromagnetic induction occurs between the rotor 35 and the stator 34, generating current, which is output through the transmission cable 36. The buoyancy of the float device 2 is determined by factors such as the weight of the float device 2, the horizontal shaft 31, and the drum device 3. When the wave-breaking power generation equipment is installed, the float device 2 floats on the water surface, and the top of the blades 33 on the upper portion of the drum housing 32 is higher than the static water level 7 at that location.
[0056] The basic working principle of the floating wave-breaking power generation device of the present invention is as follows: when in use, the floating wave-breaking power generation device is assembled in a water area where wave protection is required, for example, outside a seawall (beach) where beach protection is required, and is assembled along the seawall, with the axial direction of the horizontal axis 31 preferably being as perpendicular to the direction of the waves 8 as possible. Figure 1 and Figure 9When waves 8 are generated on the water surface and surge toward the protected embankment or shore, when the waves encounter the roller device 3, the blades 33 bear the waves 8. Under the impact of the waves 8, the roller housing 32 is pushed to rotate continuously around the horizontal axis 31. Since the wave energy is concentrated on the surface of the water, the blades 33 continuously break up the waves 8, and the large waves 8 are divided into small waves 8, which are continuously crushed. Under the action of subsequent waves 8, the roller housing 32 rotates continuously, thereby achieving the goal of constantly breaking the waves and dissipating energy, using waves to eliminate waves. In addition, when the roller housing 32 rotates around the horizontal axis 31, it drives the rotor 35 of the power generation component to rotate around the stator 34, thereby generating an induced current, which is transmitted through the transmission cable 36. In this way, the roller device 3 converts the kinetic energy of the waves 8 into mechanical energy, and then converts the mechanical energy into electrical energy, thereby realizing the use of ocean waves for power generation. Moreover, as the tide level rises and falls, the height of the horizontal axis 31 and the roller device 3 is automatically adjusted by the buoy device 2, thereby ensuring that the roller device 3 always maintains the optimal position for wave breaking and power generation, thereby solving the problem that traditional wave-breaking components can only break waves 8 below a certain tide level, and the problem that traditional power generation devices are greatly affected by the tide level and have poor power generation effect.
[0057] The floating wave-breaking and power generation equipment of the present invention can not only prevent and eliminate waves, but also generate electricity by utilizing waves. It combines wave prevention and power generation into one, turning harm into benefit, making full use of wave resources, and can automatically adjust its height as the tide level changes to ensure the best working effect.
[0058] See also Figures 1 to 9 The present invention will be further described below with reference to a specific embodiment:
[0059] In this embodiment, see Figure 1 Depending on actual needs, multiple pile shafts 1 are arranged in a straight or zigzag row. A roller device 3 is installed between the buoy devices 2 on each adjacent pile shaft 1. The buoy device 2 on the middle pile shaft 1 supports a horizontal shaft 31 on each side. The floating wave-breaking power generation equipment is arranged in a row along the shoreline of the wave-breaking area. Of course, multiple rows of floating wave-breaking power generation equipment can also be arranged as needed. In other cases, other arrangements can be used based on actual needs.
[0060] In this embodiment, see Figure 1, the pile shaft 1 can be a circular prefabricated pile or a circular steel pile, and the pile diameter, pile length and pile spacing are determined according to the design requirements. The length of the lower end of a single pile shaft 1 buried in the ground is calculated and determined according to the stability and strength requirements of the entire equipment, and the height of the pile top is determined according to the requirements of the highest tide level. The pile shaft 1 is arranged in the required area in the form of pile sinking, and its function is to serve as the support of the buoy device 2 and the vertical axis for lifting. The buoy device 2 on the two adjacent pile shafts 1 supports a horizontal axis 31, and the pile shaft 1 in the middle position can serve as the support of the two horizontal axes 31. The distance between the two pile shafts 1 is related to the stiffness and strength of the horizontal axis 31 and the roller device 3, and should be set through design calculations. Generally, a distance of 30 to 50 meters between the two pile shafts 1 is more appropriate.
[0061] In this embodiment, see Figure 1 As a preferred design, the floating wave-canceling power generation equipment also includes a lightning protection structure, including a lightning rod 4 and grounding steel bars 5. A lightning rod 4 is installed at the top of each pile shaft 1, and a grounding steel bar 5 is installed at the bottom of the pile shaft 1. Specifically, the main bar of the pile shaft 1 can be extended 0.8m beyond the pile end and sunk into the ground during the pile sinking, serving as the grounding steel bar 5. The grounding resistance of the grounding steel bar 5 is preferably less than 1.0Ω. The main bar at the top of the pile shaft 1 extends 0.1m beyond the pile end and is welded to the lightning rod 4. The lightning rod 4, the main bar of the pile shaft 1, and the grounding steel bars 5 form a lightning protection network to ensure the safety of the floating wave-canceling power generation equipment.
[0062] The buoy device 2 is a supporting member of the horizontal shaft 31 and provides the buoyancy required for itself and the roller device 3 to rise and fall with the water level. Figure 2 、 Figure 3 and Figure 4 As a preferred design, the buoy device 2 includes a closed cylindrical hollow box consisting of an inner sleeve 22, an outer sleeve 21, a bottom plate and a top plate. The cylindrical hollow box is the main component of the buoy device 2 and should meet the rigidity and strength requirements. Preferably, a reinforcing rib 23 is fixedly provided between the inner sleeve 22 and the outer sleeve 21. The inner sleeve 22 can be movably mounted on the pile shaft 1. The inner diameter of the inner sleeve 22 matches the diameter of the pile shaft 1 and is generally 0.6 to 0.8 m. Further, in the embodiment, see Figure 3 and Figure 4 As a preferred design, the inner wall of the inner sleeve 22 has a U-shaped cross-section and a groove along its circumference. Balls 26 are positioned in the groove to abut against the pile shaft 1. Multiple grooves are arranged vertically (axially) along the inner sleeve 22. The buoyancy device 2 is raised and lowered by the rolling motion of the balls 26 on the pile shaft 1, converting the sliding friction between the buoyancy device 2 and the pile shaft 1 into rolling friction, thereby reducing the resistance of the buoyancy device 2 during its vertical movement. The diameter of the outer sleeve 21 is generally around 2.0 m, determined by calculations of the required buoyancy. The cylindrical hollow box is a deep-well type cylinder, so even when the forces are unbalanced, there will be no obstruction between the buoyancy device 2 and the pile shaft 1.
[0063] In this embodiment, see Figure 2 and Figure 4 As a preferred design, a notch 24 is provided on the side of the cylindrical hollow housing. The buoy assembly 2 also includes a bearing seat 25 disposed within this notch 24, with the end of the horizontal shaft 31 mounted within this bearing seat 25. The notch 24 extends downward from the top of the cylindrical hollow housing. The depth of the notch 24 is determined by the installation of the bearing seat 25, which is in turn determined by the installation elevation of the horizontal shaft 31. The width of the notch 24 is generally no less than 700 mm to facilitate operation. For a buoy assembly 2 located on the central pile shaft 1, both sides have notches 24 and bearing seats 25.
[0064] The roller device 3 is the main component for wave dissipation and power generation. Figure 1 In order to reduce the torque of the roller device 3 during wave dissipation, minimize its deformation, and avoid mutual influence, as a preferred design, multiple roller boxes 32 are installed on the horizontal shaft 31 of the roller device 3. The length of a single roller box 32 is generally 3 to 5 meters. Each roller box 32 is equipped with the same power generation component, independently performing wave dissipation and power generation. That is, the rotation speeds of the roller boxes 32 on the same horizontal shaft 31 can be different. In addition, a limiting axis clamp 37 is fixed on the horizontal shaft 31 and located between adjacent roller devices 3. The limiting axis clamp 37 is used to separate the roller devices 3, prevent the roller devices 3 from sliding along the horizontal shaft 31, limit the axial position of the roller box 32, ensure that each roller box 32 operates independently, and avoid mutual influence between adjacent roller boxes 32. The limiting axis clamp 37 is made of an annular steel plate with a thickness of not less than about 7 mm. Its inner diameter is the same as that of the horizontal shaft 31. It is welded to the horizontal shaft 31 and has an outer diameter of not less than half the outer diameter of the roller box 32. For ease of installation, the limiting shaft clamp 37 is divided into two semicircular plates along the radial direction, which is convenient for production and assembly.
[0065] In this embodiment, see Figure 1 and Figure 5 Horizontal shaft 31 is made of steel. Its diameter is calculated based on length, deflection requirements, the drum weight it bears, and operating conditions, ensuring strength and rigidity. The deflection of horizontal shaft 31 is preferably less than 1 / 600 (1 is the fixed shaft length). To facilitate the arrangement of output wiring, horizontal shaft 31 can be made of steel pipe. The output wiring of the power generation assembly can be laid along the interior of the steel pipe to the buoy assembly 2, and then the output cable 36 is connected from the top of the buoy assembly 2. Figure 1 .
[0066] The drum housing 32 is the main component of the drum device 3. Figure 5 、 Figure 6 、 Figure 7 and Figure 8As a preferred design, the drum housing 32 includes a coaxial drum inner cylinder 321 and a drum outer cylinder 322, as well as supporting side portions 323 located at both ends. The supporting side portions 323 are rotatably sleeved on the horizontal axis 31. The drum inner cylinder 321 is coaxial with the horizontal axis 31. A waterproof structure is provided between the supporting side portions and the horizontal axis, so that the space between the drum inner cylinder 321, the horizontal axis 31, and the supporting side portions 323 at both ends is sealed, forming a storage space for installing a generator set. A closed space is formed between the drum inner cylinder 321, the drum outer cylinder 322, and the supporting side portions 323 at both ends, forming a cylindrical hollow cylinder sealed on all four sides. The drum housing 32 itself also provides a certain amount of buoyancy, and its size is based on the buoyancy requirements, i.e., drum buoyancy = total buoyancy - buoyancy of the float device 2. The drum housing 32 should meet the rigidity and strength requirements, see Figure 7 and Figure 8 As required, a plurality of reinforcing partitions 324 are provided between the inner drum 321 and the outer drum 322, as well as on the supporting side portions 323. The drum housing 32 can be made of plastic or steel.
[0067] In this embodiment, the drum housing 32 is composed of three sections, with supporting side sections 323 at either end forming the two support sections. A rolling bearing 325 is disposed in each of the supporting side sections 323, and the rolling bearings 325 are sleeved onto the horizontal shaft 31. Thus, the drum housing 32 is mounted on the horizontal shaft 31 via the rolling bearings 325 at both ends, allowing for flexible rotation. The drum inner cylinder 321 and the drum outer cylinder 322 form the middle section. A concave groove is formed between the supporting side sections 323 at both ends and the inner wall of the drum inner cylinder 321 for mounting the rotor 35 of the power generation assembly. The rotor 35 is fixed to the inner wall of the drum inner cylinder 321.
[0068] In the present invention, a waterproof structure is provided between the ends of the drum housing 32 and the horizontal shaft 31. This waterproof structure, located between the support side portions 323 and the pile shaft 1, prevents water from entering, ensuring a sealed space between the support side portions 323, the drum inner tube 321, and the horizontal shaft 31. This creates an accommodating space for mounting the rotor 35 and stator 34, ensuring the safety of the power generation components. The waterproof structure can employ a variety of commonly used sealing structures, such as sealing rings. Preferably, the rolling bearing 325 can be a watertight bearing to prevent water from entering.
[0069] In the present invention, the blades 33 are components that use the kinetic energy of the waves 8 to drive the drum housing 32 to rotate, and are also wave-breaking components. The blades 33 dispersedly arranged on the drum housing 32 constitute a wave-breaking assembly. As a preferred design, in this embodiment, see Figure 5 、 Figure 6 、 Figure 7 and Figure 8The blades 33 are arranged on the drum housing 32 to form multiple blade ring groups, which are evenly spaced and not too dense. They should have a certain spacing to form a wave 8 receiving interface of a certain width to receive the waves 8. Each blade ring group includes multiple blades 33 evenly arranged along the circumference of the drum housing 32, and can generally be set to 6 to 8. The spacing between blades 33 in the same blade ring group (the arc distance along the outer peripheral wall of the drum housing 32) is generally 0.5 to 0.8m. In addition, the blades 33 in adjacent blade ring groups are staggered, that is, the blades 33 in one blade ring group are between the two blades 33 in another blade ring group, forming a plum blossom shape.
[0070] In this embodiment, the blades 33 are curved vertical plates, similar to the blades of an axial flow pump, made of the same material as the drum housing 32 and welded to the surface of the drum housing 32. The number, length, and width of the blades 33 are determined by calculation. When the floating wave-breaking power generation equipment is assembled in water, the blades 33 on the upper part of the drum housing 32 should be higher than the static water level 7. The height above the static water level 7 should be determined based on the average wave height so that it can be sufficient to absorb most of the waves 8. Based on the characteristics that the energy of the waves 8 is concentrated in the surface of the water body, the depth to which the drum device 3 is immersed in the static water is reasonably determined to ensure the wave-breaking effect and power generation efficiency. The width of the blades 33 is preferably two-thirds of the length. In this embodiment, preferably, the blades 33 can be of different colors to increase the landscape effect. In addition, the pile shaft 1 can also be set to be colorful to form a landscape.
[0071] See also Figure 6 In this embodiment, the stator 34 in the power generation assembly is cylindrical and fixedly mounted on the horizontal shaft 31. The length of the stator 34 is substantially the same as that of the rotor 35. The rotor 35 is fixedly mounted on the inner wall of the drum inner cylinder 321 of the drum housing 32. The rotor 35 is cylindrical and coaxially surrounds the stator 34. When the drum housing 32 rotates under the action of waves 8, it drives the rotor 35 around the stator 34, generating an induced current. This current is transmitted through a transmission cable 36. The transmission cable 36 can be laid along the interior of the horizontal shaft 31, then enter the buoy assembly 2 from the end and extend to the top of the buoy assembly 2. At this point, it can be connected to external wires, and the electricity is then transmitted through the external wires. The external wires connected from the top of the buoy assembly 2 can be overhead wires or buried cables. The specifications, form, and quantity of the external wires are determined according to the electrical design requirements.
[0072] In the present invention, the power generation principle of the rotor 35 and the stator 34 in the power generation assembly is well known. The rotor 35 and the stator 34 are both composed of a combination of multiple parts. The rotor 35 is generally composed of windings, a magnetic iron core and other auxiliary parts, and the stator 34 is generally mainly composed of permanent magnets, etc. The rotor 35 and the stator 34 can specifically adopt a variety of existing structures, which will not be described in detail here.

[0074] (1) Arrangement of pile shafts 1: On the outside of the seawall (beach) where beach protection is required, a row of pile shafts 1 (prefabricated circular piles or steel piles) are driven in according to the designed pile diameter, pile spacing, and pile length; the arrangement of the pile shafts 1 can be in a straight line or a broken line.
[0075] (2) Fabrication and assembly of the float device 2: The float device 2 has the same shape and size, and can therefore be produced in a factory as a standard component, specifically including: (21) using steel plates to make parts such as the inner sleeve 22, the outer sleeve 21, the bottom plate and the top plate, and then the inner sleeve 22 and the outer sleeve 21 are coaxial and welded to the bottom plate and the top plate to form a closed cylindrical hollow box body with a stiffening plate in the middle; (22) machining a U-shaped groove, in which the ball 26 is embedded; machining a bearing seat 25; (23) welding a groove on the inner hole wall at both ends of the inner sleeve 22; (24) installing the bearing seat 25 in the notch 24 opened on the upper part of both sides of the cylindrical hollow box body; thereby completing the fabrication and assembly of a single float device 2.
[0076] (3) Production and assembly of the roller device 3: The roller housing 32 has the same shape and size, so it can be standardized and produced in the factory; a single roller housing 32 is produced in three sections and finally assembled, specifically including: (31) processing the horizontal shaft 31 according to the designed length and diameter; installing the stator 34 on the horizontal shaft 31; processing the limit shaft clamp 37 and dividing it into two semicircular plates in the radial direction; (32) processing the roller housing 32.

[0077] (4) Assembly of floating wave-breaking power generation equipment: (41) Install a single buoy device 2 on the pile shaft 1, and install a lightning rod 4 on the top of the pile shaft 1; (42) Install one end of the horizontal shaft 31 with the bearing seat 25; (43) Install a single drum box 32, first install one supporting side 323 of the drum box 32 in the box through the rolling bearing 325, and then install the middle section, make sure that the rotor 35 on the drum inner tube 321 is opposite to the stator 34 on the horizontal shaft 31, and then weld the middle section to the front supporting side 323, and then install another supporting side 323 and weld it to the front middle section to complete the installation of the single drum box 32; After the above operations, install multiple drum boxes 32 on the horizontal shaft 31.
[0078] (5) Install the other end of the horizontal shaft 31 on the bearing seat 25 of another buoy device 2, and then install the limiting shaft clamp 37 between the adjacent drum boxes 32. The limiting shaft clamp 37 is obtained by splicing and welding two semicircular plates.
[0079] At this point, the installation of a single roller device 3, that is, the installation of a single wave-breaking and power generation device is completed, and so on, the next installation is carried out.
[0080] Finally, according to the electrical design, install the control equipment and arrange the output wiring.
[0081] The floating wave-breaking and power generation equipment of the present invention first converts the kinetic energy of the wave 8 into mechanical energy through the roller device 3, drives the roller box 32 to rotate, and then uses the mechanical energy to break the wave 8, thereby cleverly using the kinetic energy of the wave 8 to reduce the wave 8, realizing a new technology of using waves to eliminate waves. At the same time, through the rotation of the roller box 32, the mechanical energy generated by the wave elimination is converted into electrical energy by the power generation component, killing two birds with one stone, using waves to eliminate waves to protect the embankment, and using waves to generate electricity to increase efficiency. Both the buoy device 2 and the roller box 32 can provide buoyancy. Therefore, both the buoy device 2 and the roller device 3 rise and fall with the tide level at the same time, always maintaining the optimal state of wave elimination and power generation, solving the problem that traditional wave-breaking components can only eliminate waves 8 below a certain tide level, and traditional power generation devices are greatly affected by the tide level and have poor power generation effects. The present invention is simple and practical, safe and reliable, and easy to install and maintain.
